Greetings, I am new to the forum. Little over three months ago I hit the top of my head in a car crash; no fainting and a spell of dizziness that appeared after a n hour or so. I've had headaches off and on since then and have had a CT Scan done and an MRI done both of which revealed nothing.

Yesterday however while I was getting up while my bus came to a stop and I hit the top of my head (again) on the steel handles.

Being a paranoid (I'm talking extremely) I was just wondering whether or not that could result in second impact syndrome. If not I was just wondering what in Good God's name it could be and if you could lend me your wisdom.

Thank you for your time.
